Package uk.ac.gla.terrier.compression

Provides implementation of a random access file and input and output streams where we can read or write gamma, unary and binary encoded integers.

Description

Interface Summary

BitIn	Interface describing the read compression methods supported by the BitFile and BitInputStream classes.
BitInSeekable	Interface for BitFile and OldBitFile - future proofing for returning new objects for readReset instead of just the object itself.
BitOut	Interface describing the writing compression methods supported by the BitFile classes.

Class Summary

BitByteOutputStream	This class provides methods to write compressed integers to an outputstream. The numbers are written into a byte starting from the most significant bit (i.e, left to right).
BitFile	This class encapsulates a random access file and provides the functionalities to write binary encoded, unary encoded and gamma encoded integers greater than zero, as well as specifying their offset in the file.
BitFileInMemory	Class which enables a BitFile to be read in memory
BitInputStream	This class reads from a file or an InputStream integers that can be coded with different encoding algorithms.
BitOutputStream	This class provides methods to write compressed integers to an outputstream. The numbers are written into a byte starting from the most significant bit (i.e, left to right).
BitUtilities	Utility methods for use in the BitFile classes.
LinkedBuffer	Implements an element of a linked list that contains a byte array
MemoryLinkedOutputStream	This class implements an OutputStream that writes everything in memory, and never flushes the data to disk.
MemoryOutputStream	This class extends an ordinary OutputStream to handle transparently writes in memory.
MemorySBOS	This class extends the BitByteOutputStream, so it provides the compression writting functions, but uses a MemoryOutputStream as an underlying OutputStream, so it is needed to be flushed to disk separately.
OldBitFile	This class encapsulates a random access file and provides the functionalities to write highly compressed data structures, eg binary encoded, unary encoded and gamma encoded integers greater than zero, as well as specifying their offset in the file.
OldBitInputStream	This class provides sequential stream access to a compressed BitFile file.
OldBitOutputStream	Deprecated.
